. in the county of'McHenr-y and State orn llinois, have jointly inventedcertain new and useful'- Improvements in TypejvFrlting-h/Ia chineFrames; and we do hereby declare that the following is a full, clear,and exact Adescription thereof, reference being had to the accompanyingdrawings, and to the let- `ters of reference marked't-hereon, which formpart of this specification.

This invention relates to improvements 1n typewriting' machines, and hasreferencey more especially to theA construction of the frame or base ofthe machine and means for supporting or sustaining the several mainoperative parts of the machine on such frame or base.

.The typcwri'ting machine tov which the present invention relates isthat kind known as an 0liver"` typewriter, and a` machine having a baseor frame of the same eneral character as 'that shown in prior atent,

4granted to Cross and Griffiths,

Qctober 30th i906, The improvements hcreindescribed and claimed arehoweverl applicable tomachines of different details of construction fromsuch Oliver Imaj chine.

The inventionfconsists inthe matters herepointed out 1n the apinafterdescribed and pended claims.

In thc accompanying drawings-Figure l is a View in central, vertical,longitudinal section of the liront or forward part of a typewritingmachine frame embodying our invention; Fig. 2 is a view in frontelevation of' the parts shown in Fig. l; Fig. 3 is a plan view of thesame with the operativeparts above the base-plate and type-bars removed,showing the typehar supporting standards inplan wlew and the type-barlinks in section; 4 is a bottom view of the parts shown in Figs. l and2; Fig. 5 is a detail View, in side elevation, of one of the type-barsupporting standards; Figs. G and 7 are detail sectional views taken onlinesv 6-6 and 7 7, respectively, of Fig. 5.

The main part or base of the machine frame comprises a horizontal,elevated top wall A, side walls A', A', made integral with and`depending from the side margins of the top-plate A, anda front wall A2.extending 'transversely of the front of the machineand made integralwith thel forward ends of the kside walls A, AC 'The topvwall A extendsbetween the rear parts'of the side walls A', A, and the forward parts ofsaid side walls are extended forward of the front edge of said topplate. The upper margins of the forward parts of the side walls are pro-`vided with inwardly extending, horizontal flanges a, lai, Fig. 3, whichforms forward extensions of the side portions of the horizontal top wallwhile the front wall A2 is provided with a rearwardly extending,ioriaontal flange a at its uppermargin, connected at its ends with theilanges a, a of theside walls` Within the vspace formed between theforward margin of the horizontal top vwall A and the flanges a, c of theside and front walls, is located the upturned or key-bearing ends B, B,of the key-levers C. C, which l'atter extend from front to rear of themachine frame and are substantially horizontal. vThe top-plate A extendsover the rear parts'v of said key-levers and supports lthe papercarriage and other-oper: ativ'e parts of the machine that are locatedjabove the key-levers.

The type-bars ot the machine are arranged in twogroups on opposite sidesot' the center if the machine, in the manner well'known in the Olivertypewriting machine, and isaid type-bars are mounted on type-bar'standards D, D which are mounted upon :the elevated horizontaltop-plate A of the 'frame or base, near the forward edge of said plate.The upright links B', B which connect the ke`ylevers C, C, with thetypebars, are located in tw'o groups at the inner and forward faces ofthe type-bar standards I), D. The'paper carriage, supporting Itheplaten, as in the @liver typewriting machine, is located at the rear ofthe said standards D, D. Parts ot' such machine, shown in the drawings,include the carriage rack-bar FJ; the shift-tramc F; the forwardcarriage-bar F', on said frame; the escapewheel shaft M, provided with agear-pinion M, which engages the carriage rack-bar E- a bracket F2 onthe shift-frame, in 7which said shaft is mounted, shift-levers G, Gtoractuating the shift-frame, which act on a transverse rock-shaft Hprovided with upwardly extending Crank arms H; the universal barK, whichis ri idly connected with a transverse. horizontal rock-shaft K',

located beneath the forward ends of the key-levers; the space key L,which is located above the top flange a. of the front wall i/ andspace-key levers L, L', that are connected with one of the arms of theuniversal bar by a link Z. y

f The machine shown is provided with devices such as have heretoforebeen employed upon the Oliver typewriting machine, towit: a column stopor tabulating device embracing tabulator key-lever N, whichisinounted'vbn, and extends forwardly from, the arm or bracket F2, and isconnected with the upper end of the escape-wheel shaft M, a right-handmarginal release device, embracing a key-lever 0 mounted on the bracketlf2 at one side of the tabulatorV keylever N, and extending forwardly.substantially parallel with said tabulator key-lever, said key-leversN'and 0 being provided at their forward ends with keys n, o, and aribbon-throw device, the base-plate P of which is supported in front ofthe paper carriage, by means of an upright standard P1 on thebracket-F2. l

y Now, referrin to the features of construction at theV orward part ofthe machine frame, by which are supported the operative parts locatedbeneath the forward ends of the key-levers, the same vembrace featuresof construction as followsz A horizontal frame plate or bar Q extendsacross the forward part ofthe frame beneath the keylevers and at adistance below the upper margins of the forward parts of the side wallsA', A of the base frame. The inwardly projecting parts a2, a2 of thesaid walls are provided upon their lower surfaces with downwardlyfacing` shoulders against which the ends of the said frame plate Q aresecured by means of screws g, g. The frame plate Q is located at itsforward ends at some distance from the front wall A2 of the base frame,so as to leave an open space between the said frame plate and the frontof the machine frame beneath the forward ends of the key-levers. A,slotted guide plate Q for the several key-levers is ar-. ranged.vertically above the rear margin of, and is supported upon, the saidfra-me pla-te Q. As shown, said guide plate is made of sheet metal andhas at its low/er edge a rearwardly bent flange which is fastened byscrews to the frame plate. The said frame plate Q., Fig. 4, is providedat its rear edge, near its ends, with integral, rearwardly ex tendingbracket arms Q2, Q2. Said bracket arms are employed to adord pivotalsupport for the rock-shaft K of the universal bar, and are also employedto afford pivotal support for two transverse rock-shafts G2, G3, whichare operated by the shift levers G, G. Said frame plate also carries, atits ends, two integral, depending,` projections or hubs Q4, Q4, to thelower ends of which are i,i iones secured rubber `disksor cushions Q5,Q, by

described, has the principal advantage of providing support for theoperative parts beneath the forward ends of the key-levers, without theemployment of the horizontal part of the base frame extending beneaththe key-levers, such as is shown in said prior Patent, No. 834,565 sothat an open space 1s afforded beneath the forward ends of thekey-levers on which the keys are moutnt/ed, through which may fall. anydust onY dirt such as is liable to accumulate beneath the front parts ofthe key-levers in case th re is a surface there located on which the"Aame may be deposited. Such a surface lo ated beneath the key-levers isdifiicult to reach tirely open, forward of the frame bg while the top ofsaid frame bar mja, easily reached through the space pro ided between'its forward edge and front wall of the machine base. The use of the ,irame bar Q, made as described, also greatly facilitates the'construction of the machiire, because the bearing brackets or arms desc,ibed, as well as the hubs which carry the elastic feet, may be easilycast thereon or made integral therewith. f

Another feature of our improvemdnt relates to the construction of thetype-bar supporting standards D. Said standards, as illustrated, havethe form of angle ba'rs hav-l ing each a fiat part (Z which cxterrdsin adirection from the front to the rear of the machine and a transversepart (Z transverse ofthe machine and extending fromI the part (Zinwardly or toward the center of the mawith an integral base plat-e D atits lower end which is preferably extended rear wardly from thetransverse vertical part d in the form of'ti foot D2, and said baseplate D is arranged to rest upon an elevated seat A4 formed on thetop-plate A to receive the same. Each standard D is also provided at itsbase or lower end with an outwardly eX- tending, rigid arm D3, whichextends laterally and outwardly over the top-plate A to a point near theouter, lateral margin of said top-plate. A vertical, transversely eX-tending rib D4 extends outwardly from the front margin of the verticalpart [Z of the standard, and is connected integrally with the frontmargin of the arm D3. The outer end of the said arm Da is connected withthe base plate by adjusting means adording rigid, but verticallyadjustable, connection of the arm with the base-plate. As shown,

for cleaning, while in the present cons ruc-l tion the space beneath thekey-levers i. env` chine. Each of the standards is'providedinteresa. .1.

Figs.

means conslsts of a screw'ol3 inserted through i said arm and havingscrew-threaded engagement therewithv and bearing at its lowerI endagainst the top of said plate A. By adjustment of the screw d* thevouterend of the said armi mayv be raised to throwthe upper ends of thestandard in a lateral direction or inwardly and outwardly, and whenthestandard has been so adjusted it may be rmly held in position bytightening the screw d3.

Horizontal `adjustment of the upper ends of the two standards in themanner described enables the type-bars carried by the standards to beadjusted accurately in position-with respect to the striking point ofthe type.

ln connection with a typewriting machine embracing the general featuresof construction shown in :the drawings, weV provide a cover or shield Sfor protecting from dust and dirt-the-,operative parts at the center ofthe machine-and forward of the paper c arriage, embracing features or'constructionas follows; Said cover or shieldvSleXtends at its baseacross. the frame or' the machine forward of the type-bar standards D,D, its base portion S- being substantially lioriron-` tal and beingarranged to overlap, at lthe rear margins of its end portions, theforward margins of the horizontal top-plate A, to which it is secured bymeans of two screw bolts s, s. At the forward part of its end marginssaid base portions S is provided with depending flanges 8', s', whichextend downwardly inside of and tit against the inner margins of theinturned iianges a of the side walls A of the base. lSaid shield alsoembraces a rear part S2 which rises from the base portion S and isshaped at its ends to conform to the inclination of the standards D, D,and at its margins is bent or directed rearwardly so as to come incontact with the iront faces of the front stifening ilanges D4 of thestandard D., In said upwardly extending part S? of the shield are formedtwo upright slots e3, S8, through which pass the tabulator and inarginalrelease levers N and O; the keys on said levers being located forward ofthe shield. Said upwardly extending part of the shield rises to a pointabove the hub of the gear pinion on the escape-wheel shaft but y{elowthe base of the ribbon-throw device, and has a rearwardlyextendinghorizontal top portion S3 which projects rearwardly over theparts below the ribbon- -throw deyice, said horizontal top portion S3 ofthe shield being provided with two fon wardly extending notches 84, 85,one to receive the standard which supports the ribbon-throw device andthe other the upright 5 and- 6, such adjustable attachingiw rearwardlyfrom the front 'linie 'by vhich said ribbon-throw device is operatedfi'j The shield` arranged as described` serves:
